WINDOW-SCAFFOLD.

`Specication of Letters Patent. i

Application led March 5, 1919. Serial No. 280,793.

To all whom t may concern.'

Be it known that I, AUGUST H. SAss, a citizen of the United States, residing at Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented a new and useful Vindow-Scaffold, of which the following is a specification.

This invention relates to window scaffolds, one of its objects being to provide a structure of this character which can be attached to a window sill readily and securely and which provides a guard and screen at each side, thus -to insure safety to the user. A further object is to provide a device of this character which can be collapsed into a compact structure when not in use and which, if desired, can be used as a step ladder.

With the foregoing and other objects in view which will appear as the description proceeds, the invention consists of certain novel details of construction and combinations of parts which will be hereinafter more fully described and pointed out in the claims, it being understood that various changes may be made in the construction and arrangement of the parts without departing from the spirit or sacrificing any of the advantages of the invention as set forth in the appended claims.

In the accompanying drawings the preferred form of the invention has been shown.

In said drawings Figure 1 is a side elevation of the device attached to a window sill, said sill being shown in section.

Fig. 2 is a plan view.

Fig. 3 is a front elevation.

Fig. 4 is a side elevation of the device set up for use as a step ladder.

Referring to the figures by characters of reference, 1 designates side members connected by steps 2 and a top member-or rest 3 in which is formed an opening 4 for the reception of a pail. Formed in the lower portions of the members 1 are elongated slots 5 into which extend lugs 6 projecting laterally from bars 7 which are mounted on the inner sides of the members 1 and are con- 50 nected at their upper ends by a cross member 8, said bars being slidable within guide loops9 on the inner sides of the members 1.

\ The lower ends of the bars 7 are curved as shown in Fig. 1 and are insertible into open- 55 ings 10 arranged in longitudinal series in the sides of a platform member 11. Arms 12 are adjustably connected to the' inner sides of the side members 13 of the platform being connected thereto by bolts 14 extending through slots'in the arms, as shown at 15 in Fig. 1. vSecured in these armsis a transverse retaining 'rod 16 projecting laterally beyond the platform and.provided, on its ends, with extension sleeves 17 so that after the platform has been placed on a window sill, these sleeves will lap the inner sides of the window casing C if said casing is of unusual width. Hooked brackets 18 are secured to the end of the platform and constitute supplemental holding means for engaging the inner side of the window sill and wall when the scaffold is in use. Strips 19 of leather or the like are secured to the bottoms of the side members 13 of the platfform and are adapted, when the platform is in operative position, to lap the outer face of the wall and to act as pads for protecting ythe wall from the abrasive action of the.

ends of the bars 7 when extended downwardly through the side members 13, as shown-in Figs. 1 and 3. The side members `13 of the platform extend rearwardly from the platform and adjustably connected to their free ends are the slotted ends 20 of braces 21, the slots in said ends receiving clamping bolts 23 which, when tightened, will hold the braces against movement relative to the members 13.

Clamping bolts 24 are extended laterally from the upper ends of the side members 1 and are pivotally engaged by the braces 21. They are also slidably engaged by longitudinally slotted guard arms 25 pivotally connected, as at 26, to the ends of guard bars 27 which are hingedly attached to the lower endsof the members 1. Thus when the bolts 24 are tightened the arms 25 are fastened against movement and the bars 27 are likewise held, as shown, for example, in Fig. 1,. Side curtains, not shown, can be secured to the arms 25, openings 28 being provided for that purpose. Hooked rods 29 are pivotally connected, as at 30 to the side members 13 at one end and the hooks thereon can normally engage eyes 31 on the same members. Under some conditions, however, the hooks can be placed in engagement with eyes on the side members 1, as shown at 32, in Fig. 4.

In using the device as a window scaffold the platform 11 is placed on the sill S of a window with the ends of the rod 16 lapping Patented Aug. 12, 1919.

the sides of the casing or, if too short, the sleeves 17 can be placed on the rod as shown so as to lap the casing. The brackets will lap the inner side of the sill as shown at 18 and by pushing down on the rod 8 the bars 7 will project through the openingsl'O'in line therewith and engage the strips 19 on the front of the sill and wall. The rods or bars 7A will fasten theY side members 1 to the platform andby tightening the bracesvand adjusting the guard arms and ybars 25 and 27 the structure willbe ready for use.

By readjusting the parts as shown in Fig. 4c the structure can be used asa step ladder. The bars 27 are adjusted against the lmembers l, the platform ll placed on end, th'e braces extended upwardly from the members l to the upper ends ofthe sides 13 Yof the platform, and the-lower 'end of the platform connected to thelower ends ofthe members l by the rods 29 which are placed inengagement With the eyes 32, Vas vdisclosed in said Fig. il. vUien the structure is not in usewit can obviously becoll'apsed readily.

What is claimed is l. The combination with-asection including steps, yand a platform section, of means slidably engaging the step section for securing said step section to the platform section and for engaging one face-@fia platform supporting structure.

2. The combination with 'afsection including steps, of' a platform Vsection detachably engaging and 'supporting the step section, means Vupon one end "of the platform section for engagingvthe inner sideiofa platform supporting structure, and means slidably connected to the step section for connecting the step section to the platform section and `for engaging the outer surface of said supporting structure.

thereon, of separate means upon the platform andfstep sections for engaging the inner and outer surfaces respectively of-a supporting structure, braces connecting outer end yof the platform section with the upper `end of the step section, guard bars pivotally connected to the lower ends of the sides of the step section, and arms for adjustably connecting the bars to the upper ends of the `sides of thestep section, said arms constituting curtain supports.

AIn testimony that I claim the foregoing fas-.my own I have fh'ereto aiiXed my signature in the presence of two-witnesses.
